Silicone oil is a common name that collectively refers to polydimethylsiloxane ingredients. It is a commonly used raw material in cosmetics.
It mainly plays the role of moisturizing and emollient in skin care products. It is low-irritation, non-allergenic, has no unpleasant smell, has good compatibility and is stable.
The price is easy for people to accept, but the disadvantage is that it is difficult to degrade in the natural environment and may have an impact on the ecology (it also depends on the amount added).
